Pull xfs fixes from Chandan Babu:

 - Fix calculation of offset of AG's last block and its length

 - Update incore AG block count when shrinking an AG

 - Process free extents to busy list in FIFO order

 - Make XFS report its i_version as the STATX_CHANGE_COOKIE

* tag 'xfs-6.6-fixes-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
  xfs: reinstate the old i_version counter as STATX_CHANGE_COOKIE
  xfs: Remove duplicate include
  xfs: correct calculation for agend and blockcount
  xfs: process free extents to busy list in FIFO order
  xfs: adjust the incore perag block_count when shrinking
